Water level gauge W-35 series

sight glassopticalstainless steel

The water level gauge is particulary suitable for all liquid media which are aggressively hot and rapidly moved in a container, but are not too much contamined. Further product information For a stirred or rapidly moved medium the water level gauge W-350/351/352/353 is acting like a damping by-pass. Depending on aggressivity and temperature various materials can be used, e.g. the type W-350 for highly aggressive media, the stainless steel type being preferred for hot and lightly aggressive liquids. The water level gauge also serves as a sight glass indicator, the switching point for the level regulation are steplessly adjustable directly on the instrument. The sight glass is made of glass or transparent plastic material (Plexi, PVC) and has a floating element fitted with a clearly visible solenoid. This solenoid serves as an optical indicating instrument and actuates at the same time steplessly adjustable reed contacts (mono-stable or on request bistable) or micro switches on its exterior face. The number of contacts fitted on the water level gauge is optional. Furthermore the water level gauge might be equipped with a protective pipe and with a drain cock for evacuation purposes.
